Can you also make video for toyota camry 2007 abs control module
@@juliecasiple1571 Hi there, sure thing, I will make the video as soon as I have a Camry with ABS problem.
Much thank sir ,at list have gained something i highly appreciate
thank you, u are doing a nice job
@@abdulrazakbello3793 Thanks a lot, I’m glad you liked the video.
Definately the best video about abs module diagnosis in the whole internet!
Thanks a lot my friend 🙏❤️
I wish I watched this video two years ago when no ones knew what was wrong with my car. Thanks for all the effort you put in this video my friend.
Glad you found the video helpful
One of the best videos in RUclips for ABS
Thanks my friend. I appreciate it
This video is fantastic. Great explanations on how to follow the circuit. Thank you for making it!
Thanks a lot 🙏👍
the way you read the diagram is just amazing. I learned a lot. Thanks
Thanks 🙏. Glad it was helpful.
New sub. here. I saw some other videos on YT showing how to repair the ABS module, but none of them explained all these details that you provided, as you explained, I think the first thing to do the correct repair is to have the proper understanding. This was a very complete and informative video. Thanks a lot.
Thanks for your feedback 🙏👍
I've been looking for this video for a very long time! Fantastically clear explanation for people who want to start their electrical journey! boundless thanks!
Hi my friend, thanks a lot for your nice comment. I’m glad you liked the video.
Ironic I found this video. Actually my ABS was having faults. My mechanic first said need to buy a new one then has to be coded. Which would have cost a fortune. I told him give me the module and I'll send it to an electronics repair place I know who are really good. They fix everything from from gpus, laptops, cpu, etcetc. Sent it to them and they found it was as you rightly pointed out a power pin supply issue. They fix3it and my mechanic fitted and ran diagnostic test. No issues. Save a ton of money too! As you said anyone that has a abs module problem said do this!
Thanks a lot for sharing your experience. I’m glad this video was helpful 😊👍
Hi would you mind sharing who you sent yours to
Thank you for your explanation of the troubleshooting of the ABS module. As I have knowledge in Electronics, Soldering, and Components this is very informative for me. If we are performing home repair on any electrically controlled device, YT is a great source for finding schematics, components, that allow us to check many things before we have to purchase a completely new part. Thank you for your in-depth analysis on the testing of this Control Module.
Thanks a lot. I'm glad you liked it.
You are a great professional, You have technique and didactics. Congratulations!
Thanks a lot my friend, I’m trying to make more helpful videos and a nice comment like this gives me the enough motivation to keep up🙏🙏🙏
Finally I found a Pro in RUclips. Thanks Bro
Thanks 🙏, glad you found the channel helpful.
If I Had A Automotive class I would definitely have watching your video I would actually have you as a guest I really appreciate that I'm 63 and going to that right now and now I'm not afraid of that module anymore not that I ever really was I have a better understanding thank you
Thanks for your nice comment, I’m very glad you enjoyed the video

Thanks a lot for your comment. May I ask what sort of fault you have on your car?
Very good explanation. Thank you very much.
🙏🙏🙏
just say thank cause it was useful for me and enjoyed your sweet persian accent👍👍
found your video helpful. Im diagnosing a 2008 lexus rx350. The code im getting states the solenoid relay faulty. I checked the fuse and they were fine. Since i ran out of time to do further diagnoses. I will return to reconfirm power supply to the harness and inspect the pins for any movement. If im lucky enough to even open it. Keep up with good informative videos. 👍🏻👍🏻👍🏻
Hi my friend, thanks for sharing your experience, I'm glad this video is helpful.
Thank you, I learn alot from you...very professional.

Great instructional session. I have the ABS light illuminated on the dash of my '02 Chev TrailBlazer 4x4, with OBD code C0267 -- "ABS Pump Motor Circuit Open". I have good continuity at the motor connector (motor and leads good), but no continuity between the battery pin (#1 your diag.) and motor ground (#10 your diag.) on the circuit board w/ no power applied: is this a normal condition because motor relay is open when unpowered, or am I likely to find a soldering fault once I open up the control module? If I apply power to the circuit board (ignition key on), can I expect to see +12V at the circuit board ABS pump motor output pin connector? I.e., is there a way to check for a pump motor "open circuit" condition on the board w/o removing the module cover? Does the ABS Pump Motor normally run for a few seconds on every "ignition on" as a test? Thanks for the great videos!
Great video! My unit passed all the continuity tests you showed here so I'll have to go to part 2.
Thanks for watching
Thank you for the video brother! Have almost the exact one..about to run tests now! Was reading a circuit fault so hopefully i can figure out why! Thanks again!
Thanks for your comment. Glad this video is helpful 👍👍
@@AutomotiveDiagnosis i ran all the tests you showed in the video and all check out ok. Do you have any other videos on the same controller? For diagnostics? Thanks
If everything is ok probably then the pump could be the issue, but also the two positive terminal, are connected to the same circuit, which means they have continuity between them, in my case I found out The positive terminal to selonoid there is no link,.
@@shafiisigera Thanks for sharing your experience.
OK, I got one minute 30 seconds into your video. You’re amazing wow thank you for sharing. I don’t think I’m up for this with my 12th grade. Education but thank you for sharing.

Well done! I learned a lot.
2012 Ford Escape, randomly the brake pedal will go to the floor while I'm stopping and I lose like >80% of my braking effectiveness, but then the brakes are fine next time I use the pedal. No ABS codes are populating, nor does the vehicle pull to either side when this happens.
After watching your videos, maybe one of the outlet valves is sticking open, or being unseated intermittently? Any suggestions how to narrow down the issue, if this could be electrical or mechanical?

The best explanation 👍🏻
Thanks my friend
Very Pro. Thanks a lot.

great video very informative
Thanks for your nice comment. Second part of this video is coming (hopefully this week) which is gonna be about testing the components on ABS Module.
Thanks for sharing the video. Referring to the 16:40 of the video about the ABS Motor Transistor. We
connect the positive voltage to drain pin of the 2N06LH5. My question is that why not connected negative voltage but positive since the 2N06L5 is N Channel Mosfet?
Great video I learn by my self electronic repairing my old cars ( I can'teffort a techniciaan like you) but is so hard to find diagrams i bought Hayness manuals and emanuals but they dont show the terminals pin out and is a nightmare to find all connections where is posible to find ? I search for siemens moduls diagrams to my peugeot which has a short some where from fuse 9 circuit in the VDO MODUL but i dont see siemens have them. Do you have any place where to find free or where is posible to buy them?
I'm following from Norway where the mechanic houre cost about 190 usd. 🥴 It will cost 2000 usd a reparation they are creazy expensive

Glad it was helpful 👍👍
Thanks for the excellent video. I'm an electronics engineer (for over 30 years) and dry joints are a prevalent issue in places that have a lot of vibration etc, just like you pointed out on the +ve supply pins. My Suzuki Grand Vitara has an ABS/ESP error so I'm suspect dry joints on the circuit board is the cause.
Question: What do you suggest you use to reseal the cover? Black auto silicone maybe?
Cheers!
Hi my friend. Thanks for sharing your experience and for watching the video. Yes, actually the black silicone is a good choice.
Thanks bro. Very usefull information ❤
Thanks my friend for watching
Very informative
Thanks 🙏
Great video sir, i have i very similar ABS module like this one from a Suzuki. Did all the checks however it seem to have a fault from the solenoid valve driver it self . DTC C1043. Very informative video .
Thanks a lot for your comment and for sharing your experience. Yes, if your have checked the power supply on the ABS module, it could be from the solenoid valve driver.

Hi, P1542 rotation rate sensor in vw jetta TT1 abs. It can be repaired?
Thanks a lot

Thanks for the video explaining the repair procedure. Is this ABS module out of a Mazda 3, BL series ? Many of these ABS modules fail on this series of Mazda 3 .
Hi there, thanks for your comment. This one was actually for Holden Captiva which is used on some other models too, but the procedure for testing is pretty much similar.
Well articulated in deed, I just love how well you explain it in a slow understanding way ,but have problem in reading some wiring diagram do you have an article on that
Hi there, thanks a lot for your comment. I believe you can find the wiring diagram in the video description. Also the 2nd part of this video is published too which can be found in the following link:

감사합니다.
Hi my friend, Thanks a lot for your kind support and for the Super Thanks, I really appreciate it. 🙏❤️
Thankyou for this video. I have a similar board totally dead. Not detecting on Can Buds. Fuses ok.
Where does the main +Ve rail start on the board.
Hi there, normally there are 3 pins for the supply voltage. One for ABS motor, one for the valves and the last low amp one for the board. What is the model of your car? Wiring diagram helps for the pin location.
Is it possible for this to short out and start a engine fire? I saw some smoke coming from my connection on a 2005 Chevy Impala SS and my brake light would not turn off, even when I turned the car off... and it caused a fire
What model of electronic brake control module is that?
i have a 2012 Cadillac SRX with ebcm model 20842710 and that module is on back order from GM. I have a code of C056D which means internal failure. What do you think the problem is with my abs ebcm. Would doing these tests help me out or should I send it in for repairs to a abs module repair place?
Hi there, thanks for your comment. This was Holden Captiva which is similar in many other cars too. this code (C056D: Electronic Control Unit Hardware) can be from wiring harness (Power and ground provided on the control unit), ABS Module internal circuit or semiconductors. So, kinda a big inspection might be needed.
Thank you for making this video. You have de-mystified the ABS functioning and explained it very well. I have a 2013 Ford F150 that shows ===ABS DTC C1440-20===Code: C1440 - Pressure Difference Transducer Circuit Failure when I scanned it. I am told that this is inside the ABS control module but did not see it referenced in your video. Can you offer any insight as to where I can find it and possibly repair it? Thank you!
Hi my friend. It is actually located inside the ABS module and the reason for not addressing in the video is that this sensor is controlled directly by the ABS unit there is not much we can do about it. Most of the time when we have this code, we have to replace the entire ABS module.
Thanks!
👍👍
Where are you finding the pinouts? I am looking for a pn0605 pinout but can’t find anything online.
Can you provide the link or website where we can print the abs diagram and website for the semiconductor that you show on your video. Much more appreciated. Great explanation and easy to learned.
Hi there, Thanks for your comment. That ABS diagram is already in the description, you can find a link to download it from google drive. I will also attached the semiconductor details as well. (Technically we can find the details for semiconductors by searching their numbers).
Thanks for making me understand how ABS module works , is it possible to do one for ECU
Yes, definitely. Also thanks for watching this video.
Thanks for this video.
🙏🙏
@@AutomotiveDiagnosis Am still waiting for videos on how to check diodes and other components on the abs control to know more about it
@@olawunmiridwan9863 Thanks for your comment and sorry for being late to make the second part of the ABS repair video. I've been busy and couldn't manage to publish the video earlier. I try to finish it ASAP.

Thanks for the excellent video!
I have a 2003 vw mk4 Golf that is not getting any abs errors or trouble codes but I cannot bleed the driver rear calliper and have diagnosed to the abs module. Looks like it could be a sticky/stuck valve. Is disassembling the module a possible way to check or confirm it’s a stuck valve? Using VCDS abs output test to check operation.
Hi there, and thanks for your comment.
It is possible to dismantle and check the valve, but as it is sometimes a long procedure so from my point of view it is better to make sure nothing else is causing this. Just one question, when bleeding the braking system equipped with ABS, we normally bleed in two steps, first of all conventional bleeding (without scan tool), then bleeding with scan tool (if that scan tool covers the function), When you do the first step, do you get brake fluid on driver rear caliper or no?
@@AutomotiveDiagnosis Nothing at the Caliper. I also disconnected the pipe at the ABS valve body for that rear caliper and there's no fluid coming out even with break pressure. All the other ports have fluid so that's why I suspect a stuck valve. I've also tried actuating the valves using a magnet but couldn't hear clicking or activation. Is alcohol and compressed air the best way to try and clean? This makes we wonder how many older vehicles are on the road with this type of issue as it doesn't through an ABS code.
@@brentredberger9437 how do you solve this problem? My abs has same problem with you. Thanks
I was unable to fix mine. I ended up getting one off of a parts car.@@x_gangsa
@@x_gangsa I was unable to repair it. I ended up getting one from a parts car.
very good friend your videos explain better than the courses I've already done I have an abs module from the fiesta 1.6 mexican 2010 giving dct communication with gatewey the defect is intermittent the defect and in the module I already put another one and the defect is corrected you have augum video about this fix for me to see
Hi there, thanks for sharing your experience. If you have replaced the module and it’s been fixed, there is internal issue, you may also watch another video for ABS module repair for internal components test. (Link in description)
